Product Details

3M™ Dual Lock™ Reclosable Fastener SJ3870 has a modified acrylic adhesive on the back of a black polypropylene reclosable fastener. Our product can be used both indoors and outside in a variety of applications, and has a slim 6.1 mm engaged thickness and long service life.

Our remarkable 3M™ Dual Lock™ Reclosable Fastener TB3870 can be opened and closed over and over, up to 1000 times before losing 50% of the original strength for repeated access or repositioning. The mushroom heads easily slide over each other allowing positioning of parts before they are snapped together to create a firm fastening attachment. When mated the black fasteners are hidden from view and leave you with an unbroken surface to help create a smooth, clean appearance. The Type 250 stem density polyolefin fastener mates to Type 170, 250 or 400, giving the user the option of different closure strength depending upon application. Suitable for indoor and outdoor use, recommended applications are for doors, flexible solar panels, headliners, access panels, signs, and display components. The fastener is backed with a modified acrylic pressure sensitive adhesive that bonds to many plastics and powder coated paints, as well as medium to low surface energy materials with little or no surface preparation. Hear the Snap “Snap!” It’s the one word that best defines this extensive line of 3M™ Dual Lock™ products. Here’s how it works - when two pieces of 3M Dual Lock Reclosable Fastener are pressed together, the stems flex and the mushroom heads slide past each other. After passing the mushroom heads on the opposing mating piece, a stem snaps up into its original position, interlocking with the opposing heads. Listen for the audible snap to signal that the fastener is engaged. The attachment formed may be as effective as screws or rivets, but will peel apart for repositioning. 3M’s reclosable fasteners are used extensively in transportation, electronics, business equipment, machinery, medical, and sign and display markets. Lose the Screws The bond is strong but can easily be detached; just pull apart to disengage and reattach as needed. This means that this product gives you a strong, hidden bond with the convenience of multiple openings and closings so you can lose the screws, rivets, hooks, bolts, zippers and other unsightly attachment methods. In short – 3M’s product is an aesthetically pleasing fastener that doesn’t sacrifice attachment strength; in fact, 3M™ Dual Lock™ Reclosable Fastener TB3870 is about five times stronger in tensile strength than 3M™ Hook and Loop™ fasteners used in comparable applications. In many cases, this attachment method also saves the user money with less material used. Additionally, there’s no need to drill holes that might weaken the part or substrate, and no tools required to assemble and remove the part. You have more options to secure, attach and connect surfaces. 3M Dual Lock Reclosable Fasteners offer quick installation and high-strength attachment, yet can be opened as easily as zippers. That functional flexibility, as well as superior aesthetics, reduced weight, and savings in labour and installation costs, make 3M innovative fasteners a popular and effective solution.
